put the first sim on your mobile...but before that follow this steps

* turn off you mobile
* remove battery for an hour
* put it back the turn it on again

* insert the 1st sim that you have made a securitycode,try to change it if its possible
* if success,try to insert the 2nd sim the enter you previous code

if ask for a "new security code" enter 12345 or your previous code

You need to telephone your mobile phone service provider and ask for the PUK code. Then put in the wrong pin 3 times and the sim card will lock. Turn the phone off and back on. When it's starting up it will ask for the PUK code. Enter the code and it will ask you to create a new pin number. The new pin number can then be used to start the phone.

Hi,

The PUK (Personal Unlocking Key) code is a code assigned to your carrier's sim card. Its usually written on the form you received when you purchased the sim card, or on the shell the sim card was attached to. If you don't have it, just go to your carrier ( eg.AT&T, T Mobile) and provide your sim card number. Once its under your name, they will provide you with the PUK code.
(Remember most sim cards have a default number of incorrect times you can enter an incorrect code before it destroys the sim, so if you don't know it, dont enter anthing until you receive it from your carrier)

Hello, Your mobile phone's sim card has a four-digit PIN code enabled by default. If you enter the PIN code incorrectly three times, a lock will be put onto the SIM card, and you need a PUK code to unlock it. If you're being asked to enter a PUK, you will need to contact your network operator to get your sim card unlocked. This is for security reasons. Note that only your mobile phone network operator can legally provide you with a PUK code to unlock your SIM card. Thank you for using Fixya

i HOPE THIS WAS SOME HELP!

hi

as youve entered the puk code, it asks for the new pin code, the default code was 1234 right? so if you are going to try the new pin code yu can either invent a new pin code or just enter the default code.

hope this helps.
